Gravel: Weight, Coverage & Types
How much gravel you need, what a yard weighs, and which type fits your project.
Calculate gravel for your project
Gravel is a loose aggregate of small stones used for driveways, drainage, walkways, and as a base under concrete or pavers. Knowing the density and coverage helps you order the right amount without paying for excess.
Most landscaping gravels weigh roughly 2,400–2,900 lb per cubic yard (1,400–1,700 kg/m³) depending on stone type and moisture. Angular crushed stone compacts tighter than rounded river rock, so it covers slightly less area at the same depth.
A typical driveway is spread 4–6 inches deep in two lifts: a coarse base (¾″ minus or crusher run) topped with a decorative or drainage-friendly gravel like #57 stone or pea gravel. French drains and dry wells use clean, washed stone with no fines so water can move through.
To estimate quantity: multiply area (ft²) × depth (ft) ÷ 27 = cubic yards, then add 5–10% for compaction and spillage.
Common uses
- Driveways and parking pads
- Walkways and garden paths
- Drainage / French drains
- Sub-base under pavers, patios, and concrete slabs
- Erosion control and ground cover

Frequently asked
How much does a yard of gravel weigh?
Between 2,400 and 2,900 pounds (1.2–1.45 US tons) for most landscape gravels. Wet gravel weighs 5–10% more.
How deep should gravel be for a driveway?
4–6 inches total, ideally in two layers: 3–4″ of compacted crusher run as a base, then 1–2″ of #57 stone or decorative gravel on top.
How much area does a ton of gravel cover?
About 70–80 sq ft at 3″ depth or 100 sq ft at 2″ depth.
